Suttavibhanga
Suttavibhanga is the first division of the Sutta Pitaka, one of the three major collections of texts within the Tipitaka, the Buddhist scriptures. The Sutta Pitaka is attributed to the Buddha and his disciples. The Suttavibhanga itself is further divided into two parts: the Bhikkhu Vibhanga and the Bhikkhuni Vibhanga. These two sections meticulously detail the monastic rules, known as the Vinaya, for fully ordained Buddhist monks (bhikkhus) and nuns (bhikkhunis), respectively.
The Bhikkhu Vibhanga outlines the 227 rules for monks and the Bhikkhuni Vibhanga details the 311 rules
